Would it be possible to fix Lori's fur color when chosing different colors for a player? Make the Laser Shield event actually spawn a screen giving the shield? Make the game not crash when putting an event on a flipped animating tile? Make the secret level swapping actually work, and not getting you stuck when you return to the original level? Fix the bug that causes multiple gems to spawn from players at times in treasure hunt mode (ie place one gem in a room and after enough hurting you'll have quite more than that)? Make hurt events/enemies actually damage your health in hosted games? Fix the bug that causes firing freeze at certain events (mentionably gem rings but also another event if I remember) crash the game?

Properly more out there. These were just bugs that I found limiting the game somewhat.
